10 Movies Nobody Could Stop Thinking About

Requiem for a Dream is one of those all-timer movies you'll probably have a crystal-clear memory of where you were the first time you watched it.

Darren Aronofsky's unforgettable adaptation of Hubert Selby Jr.'s novel is perhaps cinema's greatest treatise on the destructive power of addiction.

Aronofsky blows apart Hollywood's tendency to make drug abuse in particular seem sexy and desirable, luring audiences in with stylish, flashy, MTV-esque filmmaking only to take them on a brutal rollercoaster ride of horrors in the pic's second half.

Requiem for a Dream is such an effective deterrent against heroin that it should probably be required reading in schools - a film that despite its technical ingenuity and attractive stars holds nothing back when depicting the consequences of addiction.

It is a film you may never want to watch a second time, yet that initial viewing will leave such a shattering, bruising impression that you'll never need to.

Ellen Burstyn's Oscar-nominated performance as a woman suffering through amphetamine psychosis is truly one of the finest pieces of acting ever committed to screen, and once you've seen it, it'll stick with you for life.
